Thanks for your reply! I'm using a program called powergrep which can search regex statements and replace with what I want. So in my original example in the replace field I put '%C3%A4', but what regex can I use in the search field to match anything between href=" and " that contains ä?

Hi,I was just about to download Powergrep to try it out, then I saw it cost 120€. Oops So, let me understand: You have a folder full of html files and want to use Powergrep to search through all of these files, line for line, and replace any occurrences of foreign characters within a href attribute with their encoded version. I.e. href="wähle.html" would become href="w%C3%A4hle.html".Is that correct?
